Thelever K is for the purpose of being operated by the swell-actuatingmechanism to throw off the starting-lever L, as is well known, and inthe ordinary loom it is also arrangedto be operated by the movement ofthe weft-forkybut when my cloth-take-up stop-motion is used incombination with the weft-replenishing mechanism I prefer to arrangethis lever K so it will not be operated by, the weft-fork, as I do notwish to stop the loom, but only desire to stop the forward movement ofthe goods when the weft-thread runs out and at the same time operate thereplenishing mechanism to drive a full cop or bobbin into the shuttle.To allow this fork-plate (Z to reciprocate in the guide plate (Z and beheld in place by and without acting on the lever, I cut a groovetransversely through both of said fork and guide plates and insert alinger K, which projects from the end of the shipper-lever K and liesacross this guide-plate and holds the fork-plate from coming out.

The weft-fork is operatively connected with theweft-replenishing-actuating mechanism through the shaft r, to whichshaft the dog R is connected from the fork-plate d. v This shaft runsacross the front of the machine (see Fig. 1) under the breast-beam tothe end of the loom on which the replenishing mechanism is located. Thearm w is fixed to the outer end of this shaft and has a roll in itslower end which engages the inclined end of the lever T. T his lever ispivoted near its center at w and. is connected at its inner end to redg, which acts to raise the lever g out of engagement with the plate aand actuates the replenishing mechanism in the manner illustrated anddescribed in my patent issued March 18, 1902, No. 695,696. The balanceweight 1" is hung on shaft -r (see Fig. 3) and is for the purpose ofreturning the weft-fork and the rest of the mechanism hung on said shaftto its normal or rest position after having been thrown out by lever o.

The operation of my invention is further explained as follows: By mymethod of connecting the weft-fork plate d to the clothtake-up-actuatingmechanism as above described the weaving of thin places in the My devicefor accomplishing this is extremely simple and effective in itsconstruction and operation and has proved itself very effective whenused in connection with this type of weft-replenishing type of loom, asit allows the loom to continue running while the shuttle is beingreplenished, but stops the goods from feeding ahead until the shuttle isagain laying the filling into the web correctly, when the clothautomatically starts feeding ahead again.
